The buccal armature closely resembles that of Eledonella pygmaea but the intermediate plates of the radula are not so markedly widened. The median plate (Text Figure 60) has 3 shorter teeth lateral to the large median tooth; the inner intermediate plate is markedly narrower than the median plate and has 4 teeth. The lateral and marginal plates resemble those in the other species. The anterior median plate is shown above the other plates so as to illustrate the marked enlargement posteriorly. 494 Text Figure 61 shows the outline of the funnel organ: it is right-angled anteriorly, slightly con- cave posteriorly, with short lateral figure 60.

Chun indicates in his notes the following measurements for the specimen from Station 66b: Right 1st arm (including margin of lip) 38 mm, left 35 mm; Right 2nd arm (including margin of lip) 41 mm, left 42 mm: Right 3rd arm (starting from margin of lip) 51 mm, left 55 mm; Right 4th arm (starting from margin of lip) 42 mm, left 42 mm. The membrane between the 1st arms and between the 1st and 2nd arms extends to half the length of the arms; that between the 2nd and 3rd arms extends as far as 16 mm, , nearly a third of the length of the arm; between the 3r
